Hi all,
I am working on a project were we are designing 63' long and 53' steel trusses. We will be fabricating these trusses out of S32205 stainless steel. Typically, I would design trusses of this nature out of double angles, but in this case, the angles may not be available in that grade of steel, due to its scarcity of use and the difficult of forming shapes out of that high grade steel.
So, we may have to use bent plate as our angle shapes.
Should I design it for the exact same properties as angle? (minus the lil' sharp corner if you have to be technical)
Or do cold-bent shapes lose strength compared to hot-rolled angles?
One source told me that the strain-hardening of bending the plates would actually make them stronger? Is that true?
Thank you in advance,
Mike
